How to FIX Bosch dryer E90 Error

1. It is good to clean the filters first and make sure the sensors are also clean from dust and cloths remains. 2. also make sure the water pipe is not blocked - try to blow air with your month and listen if you hear water bubbling sound - if so - it is open and not blocked. 3. Power off the Machine. 4. Turn it on to any of the modes and as soon as you hear the machine "clicking" - before displaying the E90 Error - BANG the RIGHT side of the Bosch Drying Machine . 5. It should come back to life. The reason the machine don&work - although you clean all the filters and sensors and places. it is because some places are hard to reach. therefore by hitting and banging the machine the dirt and cloth remains - fall off and the sensors give a "good to go" to the machine to start. GOOD LUCK!
